This study attempted to examine the impact of musculoskeletal pain on pedestrian crossing using a sample that consisted of 282 aged people. The research method involved an examination of the musculoskeletal pain of the elderly using a musculoskeletal questionnaire. The subjects were also told to walk across four- and six-lane pedestrian crossings while their gait velocity, step count, and step time were measured. The research results for pain by body regions indicated that waist pain had the highest complaint rate(33.3%). When there was musculoskeletal pain in the waist and leg/foot, gait velocity also decreased and step count and step time increased. However, usage of a cane turned out to have a positive impact on pedestrian crossing. Nevertheless, no significant relationship between waist and leg/foot pain and pedestrian crossing characteristics was found. We expect there will be continuous further studies on the subject of diverse physical problems of the aged and pedestrian crossing.

The purpose of this study is to investigate musculoskeletal symptoms and job stress of physical therapists in their 20s who are responsible for therapeutic exercise and to understand the correlation between the two. This study conducted a research on 144 subjects based on the measurement tools provided by national institution. The results are as follows. Many subjects were experiencing musculoskeletal symptoms and disorder in their hands/wrists/fingers, shoulders, and waist with high proportionate of subjects experiencing the symptoms and disorder in their right hand/wrist/finger. Among job stress, job environment, job requirement, and compensation had significantly positive correlation with physical burden(r=.297~.392, p=.000). In particular, shoulder pain intensity has significantly positive correlation with job requirement, duration of pain in hand, wrist, and fingers as well as workplace culture(r=.331~.478, p=.003~.009) which indicates that musculoskeletal symptoms are some what correlated with job stress. Based on this study, it is necessary to show more concern and make an effort to manage musculoskeletal symptoms and job stress.

Purpose : The current research examines the muscle activity that happens during scaling practice subject to 20 dental hygienic students with musculoskeletal pain and then propose a basic data according to the working attitude of the Dental Hygienist. Method : The Nordic-style questionnaire is used to define experimental group with musculoskeletal pain and control group. During the scaling the surface EMG device is used to measure the muscle activity of experimental and control group. Study design : The surface EMG is measure RMS(root mean square) of suboccipital muscle, biceps brachii, upper trapezius, and brachioradialis muscle activity. Results : In the experimental group, the RMS of upper trapezius and brachioradialis is increased during scaling practice(p<0.05), but the control group's RMS is not changed(p>0.05). Conclusion : Musculoskeletal pain may contribute to increase muscle activity of neck & arm during scaling practice. In the future we think there is a need to raise the office efficiency by subjecting to dental hyginiest that are in the clinics and performing experiments.
